O'E CADDIS-FLIES DESCRIBED BY LINN^US. 733 



are opposed. Hageu has conjectured that it may be a Fsocus ; 

 and the words "antennae, leute inspectae villosse apparent; os ut 

 in reliquis cum palpis " favour this opinion; but tbe species is not 

 to be settled with certainty. I think it may be Stenopsocus im- 

 onaculatus, Steph. 



Linnaeus has furthermore described an insect as Tinea Hobev' 

 tella (No. 1394) that cannot be Lepidopterous, for neither in 

 Sweden nor in Europe is there to be found a species of that order 

 to which the description will apply. It may have been a " Fhry- 

 ganea^^ that Linnaeus had before him, and we know that he often 

 made a comparison between the PhryganecB and Lepidoptera. It 

 may therefore not be strange if we find him describing a " Phry- 

 ganea" as a" Tinea.'^ The words "antenme longissimae" may 

 therefore signify some species of Leptoceridcs. The Tineee {De- 

 geerella, Swmnmerdamella, &c.), amongst which he places the spe- 

 cies, have a striking resemblance to this family. The words " alae 

 fuscae seu nigrae, vix manifeste cinereo-inauratse, macula alba ad 

 angulum ani " are only applicable to Leptocerus aterrimus, Steph., 

 or L. dissimilis, Steph. ; but the words " antennis albis " do not 

 agree. However, the Linnaean terminology is not as accurate as 

 that of the present day, and the antennae of L. dissimilis appear 

 to be white and unicolorous if viewed in a certain light. I 

 am convinced that this is the Linnaean species ; the size is the 

 same, and the words " alse vix manifeste cinereo-auratae " indicate 

 the pale brown iridescent pubescence of the wings. 



Notes ly E. M'Lachlan. 



It was, I think, partly at my suggestion that my valued corre- 

 spondent Pastor Walleugren undertook an analysis of the Swedish 

 Trichopterous insects described by bis great compatriot. He had 

 already casually alluded to several species in his notes on those 

 described by Zetterstedt {cf. ' Ofversigt af K. Vet.-Akad. Eor- 

 bandlingar,' 1870, No. 3). The foregoing notes have especial re- 

 ference to the nomenclature adopted by me in my ' Eevision and 

 Synopsis of European Trichoptera,' now completed as far as the 

 Linnaean species are concerned. In this work I have generally 

 adopted Pastor Wallengren's already published views, on the prin- 

 ciple that a Swedish entomologist should be the best able to elu- 

 cidate the Linua;an species ; moreover I satisfied myself that thefj^. 

 views were sufficiently borne out by the original descriptionui-
